“…Differences between FA in cheeses (Table ) showed the similar trends with experimental milk (Table ). Coppa et al () and Revello Chion et al () explained that cheese processing has only a limited effect on FA variations. This result is evident in Figure showing the plot from PLS‐DA multivariate analysis.…”

The objective of this study was to compare the fatty acid (FA) profile of cheese and milk produced from cows grazing on timothy and reed canarygrass pasture or fed indoor. Twenty multiparous dairy cows were selected from a single farm in Pyeongchang (South Korea) and assigned to two experimental groups (TMR and PAST). TMR was kept indoor and fed with a total mixed ration, while PAST was maintained on timothy and reed canarygrass (70%–30%) pasture for 5 months (beginning of June–end of October). At approximately 6‐day interval during this period, Montasio‐type cheeses were produced for each experimental group, and at the same day, bulk milk for each group was collected. Chemical composition and FA profile of cheeses and milk and the texture of cheeses were carried out. The diet affected milk fat content, which was higher in PAST than in TMR (p < 0.05). The pasture feeding increased C18:0 (p < 0.01), C18:1n‐9cis (p < 0.01), C18:3n‐3 (p < 0.05), monounsaturated FA (p < 0.05) and n‐3 polyunsaturated FA (PUFA, p < 0.05), and reduced C12:0 (p < 0.01), C16:0 (p < 0.01), C18:2n‐6cis (p < 0.05), C20:3n‐6 (p < 0.05), saturated FA (p < 0.05) and n‐6:n‐3 PUFA ratio (p < 0.01) of both milk and cheese compared with those of TMR. From FA composition point of view, pasture‐based feeding system increased the healthiness of dairy products.

“…The supernatant anhydrous fat was separated and analyzed directly for FA. The FA trans-esterification was obtained using 2 M sodium methylate to start and sodium sulfate monohydrate to stop the methylation processes, according to Revello-Chion et al (2010). The FA methyl esters were analyzed by gas chromatography as described by Coppa et al (2011a).…”

The aim of this work was to characterize the fatty acid (FA) profile of milk from intensive dairy farming systems in the Po Plain (Italy) to estimate the costs of the adopted feeding strategies and to simulate the effect of supplementary premiums on the basis of milk FA composition on milk income. Twenty dairy farms with 5 different feeding strategies were studied: 3 corn silage-based systems in which cows were supplemented with a great proportion (CCH), a medium proportion (CCM), or without commercial concentrate mix (CC0), and 2 systems in which part of corn silage was replaced with grass or legume silage (HF) or with fresh herbage (G), cut and fed indoors. Bulk milk was sampled and lactating cow performance, feeding strategies and forage characteristics were recorded through a survey, 3 times during a year. The milk FA supplementary premium was calculated considering C18:3n-3 and saturated FA (SFA) concentrations, and ratio of total cis C18:1 isomers to C16:0. The CCH, CCM, and CC0 systems bought most of their dairy cow feeds off farm, which allowed them to increase milk production to 35,000 L/yr per hectare. Their low dry matter and crude protein self-sufficiency led to higher feeding costs per liter of milk (from €0.158 to €0.184), and highest income over feed cost was achieved only for milk yield performance greater than 10,000 kg/cow per year. The use of homegrown forages in HF and G increased dry matter and crude protein self-sufficiency and reduced the feeding costs per liter of milk from 9 to 22%, compared with the other studied systems, making HF and G feeding economically competitive, even for a lower milk yield per cow. The studied systems highlighted a remarkable variation in FA profiles. The concentrations of C16:0 and SFA were the highest in CCH (31.53 and 67.84 g/100g of FA) and G (31.23 and 68.45 g/100g of FA), because of the larger proportion of commercial concentrate mix in the cow diet. The concentrations of C16:0 and SFA were the lowest in CCM (27.86 and 63.10 g/100g of FA), because of low roughage-to-concentrate ratio in the cow diet, which is known to favor milk fat depression, affecting particularly these FA. The calculated supplementary premium was the highest in the CCM system, based on milk FA profiles from those herds. The HF diet was rich in forages and resulted in greater concentration of C18:3n-3 in milk (0.57 g/100g of FA) than the other systems and thus led to an increase in milk FA supplementary premium. Milk from G and HF milk had the lowest ratio of Σn-6:Σn-3 FA compared with milk from the systems based on higher corn silage proportion in the cow diet (3.71, and 3.25, respectively, vs. 4.58 to 4.78), with the lower ratios being closer to recommendation for human nutrition.

“…As C18:3 is the most common fatty acid (FA) in forage plants, the use of pasture as the main or exclusive source of animal feed provides a sustainable source of PUFAs (Palladino et al 2009). Milk and meat from animals with a pasture-based diet have higher proportions of CLA and C18:3 and lower omega-6:omega-3 ratios than products from animals with diets based on corn silage and concentrate (Revello et al 2010).…”

The milk and meat from animals with a pasture-based diet have higher proportions of CLA and C18:3 and lower omega-6:omega-3 ratios than products from animals with diets based on corn silage and concentrate. However, most of the published studies have evaluated fatty acid profiles in temperate climate grasses and the literature with tropical grasses is scarce. Thus, the aim of this study was to evaluate the morphological and fatty acid compositions in the vertical strata of elephant grass (Pennisetum purpureum Schum.) swards subjected to grazing heights (90 or 120 cm pre-grazing heights) and levels of defoliation (50% or 70% removal of the initial pre-grazing height). There were no interactions among pre-grazing height, the level of defoliation and grazing stratum. However, higher proportion of C18:3 (58% and 63%) was found in the 90-cm swards and in the half upper stratum. A higher proportion of C18:3 was associated with a higher leaf proportion and crude protein content. Thus, the upper stratum of sward or a grazing management scheme (e.g. first-last stocking) resulting in a higher proportion of leaves and crude protein both provide higher proportions of C18:3 to animals grazing in elephant grass swards.
